英文摘要	The migration of Tc-99 in unsaturated Chinese loess was investigated in-situ with a tracer method. Quartz containing H-3 (HTO) and Tc-99 ((TcO4-)-Tc-99) was introduced into the bottom of an experimental pit which was then backfilled at the field test site. Then core soil samples were taken and cut vertically into 1 cm long slices. The slice samples were analyzed by liquid scintillation techniques in the laboratory. The results indicate that the migration pattern of Tc-99 was quite similar to that of H-3 and the vertical diffusion coefficients of Tc-99 and H-3 were calculated as (4.7+/-0.4)(.)10(-2) cm(2)/d and (7.8+/-0.4)(.)10(-2) cm(2)/d, respectively.; Chemistry, Analytical; Chemistry, Inorganic & Nuclear; Nuclear Science & Technology; SCI(E); 0; ARTICLE; 2; 411-413; 258
